题目内容
17.My classmate Lucy washes her clothes at the weekend.(改为否定句)My classmate Lucydoesn'twash her clothes at the weekend.
分析 我的同学露丝周末洗衣服.
我的同学露丝周末不洗衣服.
解答 答案:doesn't wash.原句是一般现在时,主语是Lucy三单,wash是实意动词,需借助于助动词does后加上not构成否定doesn't,后加动词原形wash,故答案是doesn't wash.
点评 含有be动词,情态动词或者助动词have/has的句子转化成否定时在其后面加上not,一般实意动词的否定式,通常应根据不同时态和人称在实意动词之前加don't,doesn't,didn't等:
